CypherHound

A Python3 terminal application that contains 260+ Neo4j cyphers for BloodHound data sets.

BloodHound is a staple tool for every red teamer. However, there are some negative side effects based on its design. I will cover the biggest pain points I’ve experienced and what this tool aims to address:

  1. My tools think in lists - until my tools parse exported JSON graphs, I need graph results in a line-by-line format .txt file
  2. Copy/pasting graph results - this plays into the first but do we need to explain this one?
  3. Graphs can be too large to draw - the information contained in any graph can aid our goals as the attacker and we need to be able to view all data efficiently
  4. Manually running custom cyphers is time-consuming - let’s automate it :)

This tool can also help blue teams to reveal detailed information about their Active Directory environments as well.

Installation

git clone https://github.com/fin3ss3g0d/cypherhound
cd cypherhound
python3 -m pip install -r requirements.txt

Usage

  • ‘-u’ - neo4j user
  • ‘-p’ - password for the neo4j user (NOTE this may be stored in history if logging enabled (default))
python3 cypherhound.py [-h] -u USER -p PWD
